Overview

The Sennheiser XSW-D Portable Lavalier Set (508488) is a wireless microphone system built for creators who need professional-sounding audio without a complicated setup process. The kit pairs an ME2-II omnidirectional clip-on lavalier microphone with a compact 3.5mm mini jack transmitter and a matching camera-mount receiver. Both units come pre-paired and operate on the license-free 2.4 GHz band, so you can start recording within moments of opening the box — no frequency scanning, no registration paperwork, and no manual channel selection thanks to the built-in automatic allocation and interference management system.

Designed with portability in mind, the transmitter and receiver are remarkably small and lightweight, making them easy to tuck into a camera bag or even a jacket pocket. The transmitter clips to a belt or waistband, while the receiver mounts to a camera hot shoe via the included adapter. Built-in lithium-ion batteries deliver up to 5 hours of continuous use and can be topped up via USB during breaks or even mid-recording — a one-hour charge gets you back to 50% capacity. The set also includes a 3.5mm curled cable for connecting the receiver to your camera or recording device, rounding out a complete and self-contained wireless audio solution.
